BRAKE-BLOCK.-

Application filed November 14, 1914.

To all whom it may concern:

Be it known that I, l/VnsLnY E. VVENNER, a citizen of the United States, residing at Stone Church, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Brake-Blocks, of which the follow- With these and other objects in view the. invention consists in the novel. details of construction and arrangement of parts which will be more clearly understood from nate as the stationary block, as indicated at 1, and the removable block, as indicated at 2. It will be understood that the stationary block 1 may be secured to the brake beam in any suitable manner. As clearly shown in Fig. 1 of the drawings, the grain of wood runs in such a direction that it will be oppos site to the movement of the wheel which it is adapted to engage. By this arrangement the. block will wear a greater length of time and, if desired, may be treated with oil, creosote or other suitable preserving fluids.

The stationary block 1 is provided near one end in each side with openings 8 and near the opposite end on each side with a plurality of longitudinally spaced openings 4:- A bolt 5 extends transversely of thestationary' block forstrengthening thesame or e for forming means whereby it may besecured to the brake beam. Each of the blocks are preferably concavo-convex, as clearly shown in the drawings, and in the concaved face ofthestationary block are a plurality of openingsfi, more clearly shown in Fig. 3 ofthe drawings. The stationary block is provided I in one end with two Specification of Letters Patent.

spaced openings 7 the purpose of which will be presently described.

The removable block 2 is provided on each sidewith a plurality of longitudinally spaced openings 8 and an L-shaped hook member -9 is adapted to be inserted in the openings. A pin 10 extends from the convexed face of the removable block, as more clearly shown in Fig. 2 of the drawings, and is adapted to enter one..of the longitudinally spaced openings 6 in the concaved face of the stationary block. A groove or slot 11 is formed in the convexed face of the removable block 2 and extends from one end thereof, as clearly shown in Fig. 2 of the drawings. A wire hook member 12 is re ceived in the groove or slot 11 and may be adjusted to extend to a greater or less degree beyond the end of the block. This hook member is held in its adjusted position by means of a screw 13, the head of which extends over the sides of the spring hook member. The ends of the hook member are adapted to be received in the openings 7 of the stationary block when the two blocks are secured together.

For securing the stationary and removable blocks together I have provided the member shown in detail in Fig. 4: of the drawings which consists of a cross bar 11 and two spring arm members 15 formed with the eyes 16 and right angle extensions 17. In assembling the blocks the cross bar 14 extends across the convexed'face of the stationary block, near one end thereof, and the eye members 16 are adapted to engage the L-shaped hook members 9 on the sides of theremovable block. The spring arm members are then bent, or brought under tension, until the right angle extensions enter one of the longitudinally spaced openings 4k in the sides of the stationary block near that end opposite to the end engaged by the cross bar 1 1. 'By this arrangement it will be seen that the two blocks are securely held together. It is often necessary to adjust the removable block whereby it will more securely engage the wheel and when this is desired the right angle'extensions 17 aredisengagedfrom the openings 4 and the eyes 16 disconnected from the hooks 9. The removable block 2 is then removed and the pin 10 may be engaged in any of the longi;

greatest possible wear will be secured from the block. I have further provided a block in which a new face may beapplied when one becomes worn. I have still further adtudinally spaced openings 6 formed in the concaved face of the stationary block 1.

The hook members 9 are then. removed and hook member adjusted into suitable position.

The screw is then again tightened to securely hold the hook members, and, as above stated, the ends enter the opening 7. When the several members have been adjusted and the blocks again assembled the securing member is again placed in position, the cross bar 14 engaging the convexed face of the stationary block, the eyes 16 engaging the hooks 9, and the right angle extensions l7entering one of the longitudinally spaced openings 4. If desired, the spring holding member maybe inverted or reversed whereby the right angle extensions will enter the perforations 3. y

Having fully described the detailed construction of my device it is thought that the advantages will be readily understood. In the first place, the grain of the wood of the.

removable block runs crosswise whereby the vantages by having the removable block adjustable in relationto the stationary block. By providing the pin 10 adapted to enter one of the longitudinally spaced openings 6,

I have provided against longitudinal movement of the blocks when together'and the spring-member securely holds the two blocks together. The hook member 12 entering the perforations? connect the twoiblocks atthe end. 7 1
